This paper aims to provide a simple economic model suitable for explaining why the tragedy of the commons take place in marine living resources and for seeking how to deal with the tragedy. This economic model suggested that because of the two traits-excludability and rivalry-marine living resources has, socially optimal catch which maximizes the whole gain of participants is always less than open access catch derived from free competition between them. The discrepancy between two catches makes the stock of marine living resources fail to keep consistent and people fail to capture them sustainably. In the long run, marine living resources get extinct, which is the tragedy of the commons. This model also shows that the higher the market price of marine living resources, the more advanced technology for catching, the higher the expected price of marine living resources and the higher time preference, compared with interest rate, the faster the tragedy of the commons happens. The basic rule for policy to prevent the tragedy is to design policy so that open access catch may dovetail with social optimal catch. These policies just like total allowance catch, vessel catch limits, the issues of licences and imposition of landing fees are suggested and their effectiveness are analyzed, based upon this model.

The developing countries have a lot of dormant resources, attempting the take-off of economic growth. The theory of 'vent for surplus' and Lewis model provide a good cornerstones to analyze the effect of export and FDI on economic growth and employment. This paper attempts to do empirical test to figure out what factor is significant as the determinant of Vietnamese employment. For this test, the estimation equations are derived from the Cobb-Douglas production function. The results are that the domestic production affects the most positive employment, compared to FDI and export. Like general expectation, export does have an substantial effect on employment in Vietnam. It is also found that the absorption of technology through export is lower than that of FDI in terms of the effect of technology on employment. So it is suggested that the employment policy should be shifted toward the absorption of technology by using FDI rather than by promoting simple processing industry for export. to sustain employment and economic growth.

This paper focuses on analyzing how Chinese government policy has developed the automotive industry and changed its market structure since the establishment of Peopleʼs Republic of China. Based on literature review on major changes of government policy on the automotive industry in China, periodization was done, classified into the four eras: the era of being aided (1949-1960), the era of self-production (1960-1977), the era of joint production with foreign companies (1978-2000) and the era of market competition (2001-present). To figure out how market structure of the automotive industry has been changed by government policy, indexical approach including concentration ratio(CR) and Herfindahl-Hirshman Index (HHI) was put to use. But due to lack of data, only the time series data from 1998 to 2013 was used. It was founded that during the relatively short period, the market structure has been changed so fast, starting from oligopolistic market, passing through competitive market and returning to oligopolistic market. The latter oligopolistic market is different from the former in that Chinese auto companies are leading with the support of Chinese government.

The paper focuses on analyzing how much Korea's service industry has international competitiveness in the world market. It is of great significance to evaluate the competitiveness and to recognize its situation because the Korean government promotes FTA strategy in a positive way. Three indicators-IMS(international market share), TSI(trade specialization index), RCA(revealed comparative advantage index)-are utilized in the evaluation of Korea's service industry. The indicators show that Korea has relatively lower competitiveness in service trade on the whole unlike the goods trade. On the sectorial base, most of service sectors which are working as key inputs including business service sector, patent and information service sector, are losing the competitiveness except transportation service sector, construction service sector and finance sector which are inextricably linked to manufacturing industry. To enjoy the benefits of FTA strategy, the social infra which is able to encourage the high value-added service sector should be constructed. So education and training system should be oriented toward the enhancement of these services because they are generally embodied as human capital in the labor.

This paper presents the simple economic model designed to explain why ship finance is relatively more fluctuated than other finance. It shows that the compensation rate of risk plays a major role in determining the amount of ship finance. When economy is in boom, ship companies increase more investment in shipbuilding than other industry because compensation rate of risk gets higher. While economy slows down, it works the other way. And the estimation model which may measure the relative riskiness in the ship companies is also derived from the original model by modifying the equation through classification of the observable variables and the unobservable ones.

국제통상 : 국제무역과 소득분배에 대한 교육의 역할

유일선 ( Il Seon Yoo ) 국제지역학회 2010 국제지역연구 Vol.14 No.3

이 논문은 한 국가가 요소부존으로 인구(N), 자본(K)과 토지(Z)를 갖는다고 가정한다. 1단계로 교육은 인구와 자본을 결합하여 신지식과 신기술을 체화한‘교육노동’(educated labor)을 ‘생산’하고, 2단계로 ‘교육노동’과 ``비교육노동``(uneducated labor)을 결합하여 제조업을 생산하고 ‘비교육노동’과 토지를 결합하여 농산물을 생산하는 무역모형을 제시한다. 이 모형에 의하면 일단 무역이 시작되면 국가의 특성에서 자본증가율이 높을수록, 토지사용률이 낮을수록, 할인율상승률이 낮을수록 제조품이 수출되고 농산품이 수입되는 무역패턴이 강화된다는 것이다. 또한 자본증가율, 인구증가율, 토지사용률과 할인율의 차이가 있는 국가간 무역이 발생하면 이 무역모형은 양국의 교육노동증가율 격차는 확대되고 교육노동 상대임금 상승률은 토지사용률의 차이가 있는 경우를 제외하고 그 격차가 축소되는 것을 보여준다. 그리고 두 노동자간 소득비율변화에 대해서 무역은 명목소득 비율보다는 실질소득 비율에 더 영향을 미치고 있다는 것을 보여주고 있다. 도시지역에 교육부문과 제조업이, 농촌지역에 농업이 존재한다고 한다면 농촌지역에서 도시지역으로 인구이동현상을 교육노동자가 되기위한 것과 제조업과 농업의 한계생산물 차이로 설명할 수 있는 모형으로 확대적용할 수 있다. In this paper is two-step trade model introduced. It is assumed that countries have 3 basic factors- capital(K), land (Z)and population(N)-as national factor endowments. As the first step, education ``produces`` ``educated labor(EL)`` which embodies new knowledge or new technology by using the population and capital as inputs. As the second step, manufacturing goods is produced with EL and uneducated labor(UL), and agriculture goods with land and UL. According to this model, the higher the increase rate of capital in a country is, the lower the usage rate of land is, the lower the increase rate of discount is, the country tends to export the manufacturing goods and import the agriculture goods. Trade widens the discrepancy of increase rate of EL in both countries but reduces the gap of increase rate of relative wage of EL as far as the gap of usage rate is not so big. Trade also affect real income rather than nominal income. This model can be extended to explain the migration from rural areas to urban areas when the manufacturing sector and education organization exist in urban area while the agricultural sector exist in rural area.

국제무역과 소득분배에 대한 교육의 역할

In this paper is education recognized as the process of producing new knowledges and technology by combining persons (N) with capital (K) which are embodied in skilled labor. Given this concept of education, it is assumed that countries have basic factors- capital, land (Z), persons-as national factor endowment. The structure of this model is that the combination of persons with capital through education segregates them into two groups-skilled labor and unskilled labor (L) with which manufacturing goods is produced and agriculture goods is produced with land and unskilled labor. When trade begins, this model shows how the differences in factor endowment and affect skilled labor, unskilled labor and the relative wage of two labors and determine trade pattern. The country which experiences faster capital accumulation, less usage in land or lower increase of interest rate will tend to export manufacturing goods and import agriculture goods. With trade the above three characteristics of a country cause skilled labor to increase and its gap between two trade countries to be bigger. But the gap of real income in terms of manufaturing goods between labors is getting smaller.

국제통상 : 한,중 서비스 무역의 수출경쟁력 비교분석

유일선 ( Il Seon Yoo ),김영환 ( Young Hwan Kim ) 국제지역학회 2009 국제지역연구 Vol.13 No.2

한국과 중국 모두 세계시장에서 재화무역에서는 수출경쟁력이 있고 서비스무역에서는 경쟁력이 없으나 양국은 서비스무역 비중이 확대되고 있고 FTA논의를 통해 양국간 서비스무역은 더욱더 확대될 전망이다. 이런 배경 하에서 본 논문은 한ㆍ중간 서비스산업의 부문별 수출경쟁력을 측정하는데 그 목적이 있다. IMF의 BOP 통계수치를 이용하여 한?중 양국의 서비스 무역에 대한 수출경쟁력을 측정하기 위해 무역특화지수(TSI), 수정현시비교우위(RSCA)지수와 국제시장점유율(IMS) 및 수출증가율을 사용해서 서비스무역의 국제경쟁력을 부문별로 비교분석하였다. 그 결과 한국은 운송서비스, 금융서비스, 특허권 등 사용료, 개인?문화?오락 부문 등 4개 부문에서, 중국은 여행서비스, 통신서비스, 보험, 컴퓨터 및 정보, 기타 사업서비스 부문 등 5개 부문에서 국제경쟁력을 가지는 것으로 평가되었다. 건설부문은 비교우위를 판정할 수 없었다. 그러나 중국이 비교우위를 가지고 있는 통신서비스와 컴퓨터 및 정보서비스부문은 비교우위격차가 축소되어 서비스무역의 국제경쟁력 강화노력이 이루어지면 중국보다 경쟁력에서 우위에 설 수 있다. When it comes to current balance, both of Korea and China enjoy the trade surplus in goods while both countries suffer trade deficit in service. This facts demonstrate that two countries have comparative disadvantages in service industry. In order to identify the international competitiveness of trade in service between Korea and China, several indexes such as TSI, RSCA and IMS was calculated, using the IMF`s balance of payments (BOP) statistics as proxy. The results of this analysis are as follows. Korea has a comparative advantage in four sectors (Transportation services, Financial services, Royalties & license fees and Personal?cultural?recreation), while China has a comparative advantage in five sectors (Travel, Communication services, Insurance services, Computer & information services and Other Business services). Construction services are indeterminate. However, the competitiveness of the two sectors-communication and computer & information-which China has a comparative advantage will be transferred to Korea if some effort to reinforce the competitiveness is added because the gap is being narrowed.

중력이론을 이용한 서비스무역의 결정요인 분석

유일선(Il-Seon Yoo),김영환(Young-Hwan Kim) 한국무역연구원 2013 무역연구 Vol.9 No.3

The importance of the service trade is highly emphasized as the international trade volume has increased along with the globalization of the economy. It is also expected that the service trade will be more expanded because the value added ratio which it has created accounts to over 70%. I made an attempt to find out what factors has promoted the service trade. Gravity model was utilized in doing that with OECD Statistics on International Trade in Services, which covers all of 34 OECD members. It is found that just as the implication of monopolistic competition model suggests, the GDP of both countries contributes to the expansion of the volume in service trade. It is also found that cultural accessibility and economic freedom have a meaningful effect on service trade between the two countries. Consequently, in order to scale up the service trade in Korea, the policies which seek economic growth, economic freedom and regard cultural factors for the expansion of service trade are required.
